I am developing an application for DICOM medical image segmentation using Qt, VTK, and ITK. My goal is to segment teeth and bones from the DICOM images. I have set up my project with Qt for the GUI, and sucessfully loaded and viewed dicom on GUI using VTK.

I would appreciate any guidance on how to achieve segmentation of teeth and bones using these tools. Specifically, I am looking for a appropriate method to achieve this.

What kind of preprocessing (e.g., filtering, thresholding) should be applied to the DICOM images to enhance the visibility of teeth and bones?

Any example code or references to similar projects would be extremely helpful.

Thank you in advance.
